A moment of inattention while operating
power tools may result in serious personal
injury.
b) Usepersonalprotectiveequipment.Always
wear eyeprotection.
Protectiveequipmentsuchasdustmask,non-
skid safety shoes, hard hat, or hearing
protection usedfor appropriate conditions
will reducepersonalinjuries.
c} Preventunintentionalstarting.Ensurethe

Powertools aredangerous in the handsof
untrainedusers.
e) Maintain power tools. Check for
misalignmentor bindingof moving parts,
breakageof partsand any othercondition
thatmayaffectthepowertool'soperation.
If damaged,have the power tool repaired
beforeuse.
Many accidents are caused by poorly
maintained powertools.
f} Keepcuttingtoolssharpandclean.
Properlymaintainedcuttingtoolswith sharp
cutting edgesare less likelyto bind and are
easierto control.
g) Usethe powertool,accessoriesandtoolbits
etc. in accordancewith theseinstructions,
takingintoaccounttheworkingconditions
andtheworkto beperformed.
Useofthepowertool for operationsdifferent
from those intended could result in a
hazardoussituation.
5} Batterytooluseandcare
a) Rechargeonlywiththe chargerspecifiedby
themanufacturer.
A charger that is suitable for one type of
battery pack may create a risk of fire when
usedwith another batterypack.
b) Use power tools only with specifically
designatedbatterypacks.
Useof any other battery packsmaycreatea
riskof injury andfire.
c} Whenbatterypackisnotinuse,keepitaway
from other metal objectslike paperclips,
coins,keys, nails,screws,or other small
metal objects,that canmakea connection
fromoneterminaltoanother.
Shortingthe batteryterminalstogether may
causeburnsor afire.
d) Under abusiveconditions, liquid may be
ejectedfrom the battery;avoidcontact.If
contactaccidentallyoccurs,flushwithwater.
If liquid contactseyes, additionally seek
medicalhelp.Liquid ejectedfrom the battery
may causeirritation or burns.
6} Service
a) Haveyourpowertoolservicedbyaqualified
repair person using only identical
replacementparts.
This will ensurethat the safetyof the power
tool ismaintained.
-WARNING-
To reduce the risk of injury, user must read
instructionmanual,
01Eng WH18DSDL US.p65 4 10/2/12, 2:38 PM

WARNING:
Some dust created by power sanding, sawing,
grinding, drilling, and other construction activities
containschemicalsknowntothe StateofCalifornia
to causecancer,birth defectsor other reproductive
harm.Someexamplesofthesechemicalsare:
• Leadfrom lead-basedpaints,
• Crystallinesilicafrom bricksandcementandother
masonryproducts,and
• Arsenic and chromium from chemically-treated
lumber.
Your risk from theseexposuresvaries,depending
on how often you do this type of work. To reduce
your exposureto thesechemicals:work in a well
ventilated area, and work with approved safety
equipment, such as those dust masks that are
speciallydesignedtofilter out microscopicparticles.
SPECIFIC SAFETY RULES AND SYMBOLS
1. Holdpowertoolsby insulatedgrippingsurfaces,
whenperforminganoperationwherethefastener
maycontacthiddenwiring.
Fastenerscontacting a "live" wire may make
exposedmetal partsof the powertool "live" and
couldgive theoperator anelectricshock.
2. ALWAYSwearearprotectorswhenusingthetool
for extendedperiods.
Q Prolongedexposure to high intensity
noisecan causehearing loss.
3. NEVERplace handsor other body parts nearthe
drill bitor chuckduring operation.Holdthe impact
driver/wrenchby itshandleonly.
4. Because the cordless impact driver/wrench
operatesbybatterypower,beawareofthefactthat
it canbeginto operateatany time.
5. WhenworkingatelevatedIocations,clearthearea
of all other people and be aware of conditions
belowyou.
6. NEVERtouch moving parts.
NEVERplace your hands,fingers or other body
partsnearthe tool's moving parts.
7. NEVERoperatewithout all guardsin place.
NEVERoperate this tool without all guards or
safety features in place and in proper working
order. If maintenance or servicing requires the
removalof a guardor safetyfeature, be sure to
replacetheguardor safetyfeaturebeforeresuming
operationof the tool.

handleis cracked.
Cracksin thetool's housingor handlecan leadto
electricshock.Suchtools shouldnotbe useduntil
repaired.
13. Bladesandaccessoriesmust besecurelymounted
to the tool.
Prevent potential injuries to yourself or others.
Blades,cutting implementsandaccessorieswhich
have beenmounted to the tool should besecure
andtight.
14. NEVERusea tool which isdefectiveor operating
abnormally.
If the tool appears to be operating unusually,
making strange noises, or otherwise appears
defective,stop using it immediately and arrange
for repairsby aHitachiauthorizedservicecenter.
15. Carefullyhandlepower tools.

If the nut is only loosely fitted to the bolt, the bolt
may turn with the nut, therefore mistaking proper
tightening. In this case, stop impact on the nut and
hold the bolt head with a wrench before restarting
impact, or manually tighten the bolt and nut to
prevent them slipping.

OPERATIONAL CAUTIONS
1. Restingthe unit after continuouswork
After usefor continuous bolt-tightening work, rest
the unit for 15 minutes or so when replacingthe
battery. Thetemperatureofthe motor,switch,etc.,
will riseifthework isstartedagainimmediatelyafter
batteryreplacement,eventuallyresultingin burnout.
Ak CAUTION
Donot touchthe metalparts,asit getsveryhot
duringcontinuouswork.
2. Cautionson useof the speedcontrol switch
This switch has a built-in, electronic circuit which
steplesslyvariesthe rotationspeed.Consequently,
when the switch trigger is pulled only slightly (low
speed rotation) and the motor is stopped while
continuously driving in screws,the componentsof
the electronic circuit parts may overheat and be
damaged.
3. Usea tighteningtime suitablefor the screw
Theappropriatetorqueforascrewdiffersaccording
tothe materialandsizeofthescrew,andthematerial
beingscrewedetc.,sopleaseuseatightening time
suitable for the screw. In particular, if a long
tighteningtime isusedinthecaseofscrewssmaller
than 5/16" (8 mm), there is a dangerof the screw
breaking,so pleaseconfirm thetightening time and
the tightening torque beforehand.

4. Work at a tighteningtorque suitable for the bolt
underimpact
The optimum tightening torque for nuts or bolts
differswith materialand sizeof the nutsor bolts.
An excessivelylargetightening torque for a small
bolt may stretchor breakthe bolt. The tightening
torqueincreasesin proportiontotheoperationtime.
Usethe correct operatingtime for the bolt.
5. Confirmthe tightening torque
Thefollowing factors contribute to a reduction of
the tightening torque. So confirm the actual
tighteningtorqueneededby screwingupsomebolts
beforethe job with ahandtorque wrench. Factors
affectingthe tightening torque areasfollows.
(1)Voltage
When the discharge margin is reached, voltage
decreasesandtightening torque is lowered.
(2)Operatingtime
Thetighteningtorqueincreaseswhentheoperating
time increases.Butthe tightening torque does not
increaseabove a certain value even if the tool is
drivenfor a longtime.
(3)Diameterof bolt
Thetightening torque differs with the diameter of
the bolt. Generally a largerdiameter bolt requires
largertighteningtorque.
(4)Tighteningconditions
Thetighteningtorquediffersaccordingtothe torque
ratio,class,andlengthof boltsevenwhenboltswith
the same size threads are used. The tightening
torquealsodiffersaccordingto the conditionof the
surfaceof workpiecethrough which the bolts areto
betightened. Whenthe bolt and nut turn together,
torque isgreatly reduced.
(5)Usingoptional parts(WR18DSDL)
Thetightening torque is reduceda little when an
extensionbar,universaljoint oralongsocketisused.
(6)Clearanceofthe socket(WR18DSDL)
A worn or deformedhex. or a square-holedsocket
will not give an adequate tightness to the fitting
betweenthe nut or anvil,consequentlyresulting in
lossof tightening torque.
Usinganimproper socketwhich doesnot matchto
the bolt will result in an insufficient tightening
torque.
(7)Tighteningtorquevaries,dependingon thebattery's
chargelevel.

Ak CAUTION:
Usingthis power tool with loosenedscrews is
extremelydangerous.
Maintenanceof the motor
The motor unit winding is the very "heart" of the
powertool.
Exercisedue careto ensure the winding does not
becomedamagedand/orwet with oil or water.
Inspectingthe carbon brushes(Fig.14)
The motor employs carbon brushes which are
consumable parts. Since and excessively worn
carbon brush can result in motor trouble, replace
the carbonbrush with newones when it becomes
worn toor nearthe "wear limit". Inaddition,always
keepcarbonbrushescleanandensurethattheyslide
